windows-2025: CMake + Ninja + MinGW GCC compilation fails #13191
Description
Description
Some time after Oct. 15th our build/test pipelines have broken on windows-2025. I tried changing to windows-2022 and that works.
We use CMake with Ninja and GCC.
Running locally with CMake 4.1.1, Ninja 1.13.1 and GCC 14.3 / MinGW 13.0 also works.

Repro steps
Sorry, this is private company repos in Azure DevOps.
If necessary I'll provide a separate minimal example.
The CMake build scripts are fairly simple. The CI pipeline is as follows:
trigger:
- develop
pool:
vmImage: 'windows-2025'
steps:
- checkout: self
submodules: true
persistCredentials : true
- script: |
cmake --preset release
cmake --build --preset release
env:
HTTP_AUTH_BEARER_TOKEN: $(System.AccessToken)
displayName: 'Build'
- script: |
ctest --preset release
displayName: 'Test'
